vpn between cisco1751's (IPsec)

c-calderon
Level 1
Level 1

I've experiencing problems setting up a VPN (IPsec based.)

Hardware: two cisco1751 (isdn)

IOS version 12.1(3)XT2

Configuration: IPsec (auth & confidentiality), isakmp (preshared key method)

The system works perfectly if not using IPsec.

The problem seems to be related to the ike-isakmp phase.

The debug shows (among a lot of lines...) the next message:

1w0d: ISAKMP (0:4): sending packet to 192.168.20.2 (R) QM_IDLE

1w0d: ISAKMP (0:4): deleting node -1586022159 error FALSE reason ""

I can't find out where the problemis, maybe someone out there can give me a hand...

Thanks in Advance!

The debugs you've quoted did not capture what could be causing the issue.

Some sample config might help you out on:

The whole debugs and config is needed to get you a clue. Maybe be best to be taken as a case with TAC.

type "debug crypto is" at the prompt and see what the output gives you.

I'd already did it... first of starting this conversation. In fact the two lines I wrote were part of the execution of this command.

Anyway, thanks for your attention!

Now, I've solved my problem.
